Step-by-step Preparation of Ground Beef Zucchini Casserole
Making a scrumptious ground beef zucchini casserole is not only straightforward but also a delightful way to impress friends and family. Here’s how to prepare this comforting dish in just a few easy steps!
Prepare your zucchini
First things first—let’s make sure our zucchini is ready for action! Start by slicing two medium zucchinis into approximately ½-inch rounds. This thickness allows for a perfect blend of texture as they cook. To remove excess water (a crucial step for achieving that luscious casserole consistency), place the zucchini slices in a sieve or colander, sprinkle them generously with kosher salt, and let them sit for about 15 minutes. After that, rinse the slices under cold water to eliminate the salt, and pat them dry with a paper towel. This will ensure your casserole won’t turn out soggy and maintain those satisfying layers.
Cook the aromatics and ground beef
Next, heat up a tablespoon of olive oil in a large skillet over medium-high heat. Add a small, diced onion and let it sauté until it starts to soften—this usually takes about 2 minutes. Now, here comes the star of our dish: the lean ground beef! Toss in a pound of ground beef and break it up as it cooks, stirring frequently until it’s browned with no pink remaining (around 5 minutes will do). To add that Italian flair, mix in two teaspoons of Italian seasoning, along with ½ teaspoon each of kosher salt and black pepper. Finally, stir in a 28-ounce can of drained diced tomatoes and remove the skillet from heat. This hearty meat mixture is the base of your ground beef zucchini casserole and smells heavenly!
Layer the ingredients in the baking dish
Preheat your oven to 350°F. Grab an 8x8 baking dish (or a 9x13 for a thinner casserole) and begin assembling your creation. Start by spreading half of the ground beef mixture evenly on the bottom. Next, layer half of the zucchini slices on top, followed by half of your shredded mozzarella cheese. Repeat the layering process with the remaining meat mixture, zucchini slices, and cheese. This stacking of deliciousness ensures that every bite is bursting with flavor!
Bake and let it rest
Now it’s time to let the magic happen in the oven! Bake your casserole for 20 to 25 minutes, or until the cheese on top is melted and beginning to golden. After taking it out of the oven, resist the urge to dive right in—allow the casserole to rest for about 10 minutes. This resting period makes it much easier to slice and serve, enhancing the overall experience.
Serve and enjoy!
Finally, serve your delicious ground beef zucchini casserole with a side salad or some crusty bread, if desired. Each bite will be a comforting blend of flavors, perfect for a family dinner or meal prep for your busy week ahead. Enjoy the compliments that are sure to follow!

Variations on Ground Beef Zucchini Casserole
Add a Crunchy Topping
Give your ground beef zucchini casserole an exciting twist by adding a crunchy topping! Consider mixing breadcrumbs with Parmesan cheese and herbs for a delightful texture contrast. Just sprinkle this mixture on top of the casserole before baking for an extra layer of flavor. You could even use crushed crackers or a sprinkle of crispy fried onions to change things up!
Swap Ground Beef for Turkey or Chicken
For a lighter version of this dish, swap out the ground beef for turkey or chicken. Both options provide a deliciously lean protein source while maintaining that hearty, comforting allure. If you opt for ground turkey, be mindful to season it well, as it tends to be milder. This simple swap can be a fantastic way to cater to various dietary preferences!
Remember, creativity is key in the kitchen—don’t hesitate to experiment and make this zucchini casserole your own!
Cooking Tips and Notes for Ground Beef Zucchini Casserole
Avoid sogginess with zucchini
To ensure your ground beef zucchini casserole doesn’t turn out soggy, remember to salt your zucchini slices.

This brief process will make a world of difference!
Make it ahead for quick weeknight dinners
Preparing the ground beef zucchini casserole can be a breeze! You can cook the meat sauce, slice the zucchini, and shred the cheese the day before. Just store everything separately in the fridge, then quickly assemble and bake when you're ready for a home-cooked meal.
